  • Patent number: 12292684
    Abstract: A method is provided including forming a first layer over a substrate and forming an adhesion layer over the first layer. The adhesion layer has a composition including an epoxy group. A photoresist layer is formed directly on the adhesion layer. A portion of the photoresist layer is exposed to a radiation source. The composition of the adhesion layer and the exposed portion of the photoresist layer cross-link using the epoxy group. Thee photoresist layer is then developed (e.g., by a negative tone developer) to form a photoresist pattern feature, which may overlie the formed cross-linked region.

  • Publication number: 20230367218
    Abstract: In a method, a resist material is dispensed through a tube of a nozzle of a resist pump system on a wafer. The tube extends from a top to a bottom of the nozzle and has upper, lower, and middle segments. When not dispensing, the resist material is retracted from the lower and the middle segments, and maintained in the upper segment of the tube. When retracting, a first solvent is flown through a tip of the nozzle at the bottom of the nozzle to fill the lower segment of the tube with the first solvent and to produce a gap in the middle segment of the tube between the resist material and the first solvent. The middle segment includes resist material residues on an inner surface wall of the tube and vapor of the first solvent. The vapor of the first solvent prevents the resist material residues from drying.
